polycount sponsor
Okay what the hell, I just got this card in my new dell and it can barely run crysis warhead with medium settings? This card is supposed be awesome anyone have experience with this card or what driver to use for it. I have the latest drivers installed. I should mention I'm running windows 7 64bit if that makes a difference.

Maybe look around on the ATI forums (I assume those exist) for people with similar issues?
note that ati ssao doesnt work properly with dx 10/11, so turn it off or use dx9, your grainy look might be a consequence of this.
FOR THE CRap performance just run a benchmark (just google one of them) and see if your scores match with any review of the 5870 (anandtech.com, guru3d.com etc)
if scores are lower try updating all the drivers of your pc
hope this helps
Also you mention "new pc from dell no previous video card install"
So this came with built in Intel graphics and you bought the card separate?
Did you::
Update the Bios for the MB. (see dells site)
Disable the onboard graphics in bios if possible.
Uninstall the Intel video drivers. (use REVO uninstaller to do it throughly)
Another thought:
If it had no graphics card installed previously (ie inboard graphics). That means the Power supply isn't leaving any headway for a Monster Card like you have. So in short, you may be underpowering the card as well.
as for ssao i just remember 5xxx had problems with some games/dx used on a couple net reviews when card came out, note that certainly ati does support it properly ,dont worry about that , it is just prolly restricted to some games and or drivers version. my intention wasn't telling you ati ssao was faulty, but the grainy effect could be related to that , especially when talking about visual quality, from my expirience ati is a bit ahead over nvidia.
as for win7 it does have dx11 yes but it also support dx 9 and 10/10.1.
and as oxynary said if your motherboard got integrated videocard be sure to disable it on the bios.

Lucky yours can actually run anything, I had two XFX ones and they just completely locked up after 5-10 mins of running like a bag of shit on my new machine, so I bought a nvidia instead and not looked back. I even tried it on two different operating systems and got same effect with them, I've not had a ATI in the last 6-7 years and thought I'd go with the nicer cards they did this time around, but was a big mistake really.

No offense, but you bought a dell. Unless you reinstalled the OS by hand without their bloatware. There may be other things interfering.
Unless your PC is broken or you decided to "tweak" the BIOS everything should go smoothly from that point.
And if not, I found Dell always very helpful in replacing broken stuff. Not sure why everybody doesn't like them, but maybe I was just lucky
Glad I'm an nvidia fanboy now!
I'm sure its fast. It can be faster without the bloatware if nothing else. Your also setting yourself up for more pain in the future when you have all the items you want installed, but try to install something else to find there is a conflict or slowdown with the Dell programs. You having this issues with the ATI is already showing something is awry. I don't have faith in Dell to release a unbuggy system that they have verified for speed/stability with their bloatware before releasing to public. So then you have to reinstall the OS, and all your programs. Versus doing it now before you get totally settled.
And hey, if nothing else, a clean install would show if there is something hardware wrong with the card or system. Right now you have too many variables, and trying to blame what you think its the obvious candidate. Its not always so black and white.
